Still have problem using physics::World::RemoveModel function

edit

Hi

I saw the post: http://answers.gazebosim.org/question/6706/gazebo-aborts-with-boostlock_error-when-removing-a/

So I updated my gazebo to 4.0, which is installed from the Debian package. When I tried to use RemoveModel function, I got two types of errors.

At the beginning, the error is:

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::lock_error> >'
  what():  boost: mutex lock failed in pthread_mutex_lock: Invalid argument

The backtrace information is:

Program received signal SIGABRT, Aborted.

Later I received different type of error message for the same code:

gzserver: /usr/include/boost/smart_ptr/shared_ptr.hpp:653: typename boost::detail::sp_member_access<T>::type boost::shared_ptr<T>::operator->() const [with T = gazebo::physics::Entity; typename boost::detail::sp_member_access<T>::type = gazebo::physics::Entity*]: Assertion `px != 0' failed.

The backtrace information is:
